OIL-BURNER} SPECIFICATION forming part of Letters Patent No. 760,826, dated May 24, 1904.

Application filed January 27, 1904.

steam or generate heat for any purposes; but

it is designed particularly to generate steam for locomotive, stationary, and marine boilers.

It consists ofa metal conduit having separate passages, one or more to convey the fuel and oneor more to convey the steam, compressed air, gas, or otherj'vapor, or combination of the same, to be used in spraying or spreading the fuel or supplying oxygen tothe fire. I

The particular feature of this device consists in combining the fuel and vapor on or above a lip or plane having a smooth or irregular surface projecting in front of the oil and steam discharge and slightly below the latter for the purpose of more thoroughly mixing the discharge or controlling its movement before passing into the fire.

Our invention. also comprises details of construction which will be more fully explained by reference to the accompanying drawings, in which:

Figure 1 is a plan view. Fig. 2 is a longitudinal vertical section. Fig. 3 is a transverse section. Fig. 4 is aview showing smooth surface on lip.

Itis the object of our invention to provide a device for the combustion of oil or petroleum product in which we are enabled by the relative arrangement of the oil and steam discharge openings and of a substantially parallel smooth or corrugated lip projecting and forming a shelf slightly below the steam discharge to more thoroughly combine the steam with the fuel and vapor and to more finely atomize the oil, so that we produce a milder flame at a lower velocity and reduce Serial No. 190,864. on mhdel.)

.the flash and noise, as well as giving a better distribution of the heat. a

As shown in the drawings, the conduit A has oil and'steam passages 2 and 3, the oilpassage located above the steam-passage, and at the rear end of the conduit each of these passages is screw-threaded or otherwise constructed for the connection, respectively, of an oil and a steam supply pipe. The steam and oil flow through the passages 2 and 3 substantially parallel, the oil-passage above the steam-passage.

The oil-conduit has a substantially rectangular opening 3 at the front, said. opening having its greatest length horizontal and its transverse depth vertical. The upper part or roof of this conduit is curved downwardly, as shown at 4, and the floor is similarly curved, as shown at 5.

The steam-conduit has a narrow and transversely-elongated slit 6, through which steam is discharged, and the .oil flowing easily over the steam-discharge opening slightly below and substantially parallel with the plane of discharge of said opening. Thislip or surface may be smooth, transversely corrugated,

or otherwise formed with an irregular surface. corrugations as extending in straight lines transverse to the plane of discharge, and the front edge of the lip is segmentally curved, as shown at- 8.

In order to confine the discharge and prevent its flowing off the sides, we have shown a raised extension 9 upon each side of the lip, this extension having a height approximating the lower edge of the steam-discharge slit.

By the peculiar arrangement of the steam and oil discharge passages and the extension or lip we are enabled more thoroughly to atomize andpulverize the oil and accomplish its intimate mixture with the steam or equivalent selastic fluid discharged under pressure. This result is more perfectly accomplished by reason of the broad transverse discharge-openings and the peculiar shape of the oil-discharge,

In the present case we have shown the which causes it to flow gently down upon the constantly-dischargi'ng sheet of steam, the lip or table extending to the front having a breadth substantially equal to that of the discharge-sheets of steam and oil and being 16- catedslightly below the plane of the steam-discharge, with the curved front and the side walls or extensions to prevent the oil from throwing off the sides of the lip.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. An oil-burner having in combination a plurality of substantially parallel conduits for oil and steam said conduits having their discharge ends terminating in substantially the same vertical plane and said oil-discharge end having its upper and lower edges curved downward to direct the discharging oil across the discharge end of the steam-conduit, and an uncovered lip or table extending to the front of the steam and oil discharge and made imperforate and with its top surface horizontal and substantially parallel with the plane of the steam-discharge and slightly therebelow.

2. An oil-burner having in combination a plurality of conduits for oil and steam, the latter located above the former and each having a broad horizontally-disposed dischargeslit at the front end, and said oil-conduithaving a down curved upper and lower portion at said front end, and an imperforate lip or table having a horizontal upper surface parallel with and slightly below the steam-discharge, and having side walls and a transversely-curved front edge.

3. An oil-burner comprising a metal conduit having substantially parallel horizontal steam and oil passages, the latter located above the former, and means for supplying steam and oil at the rear of said passages, an imperforate extension lip or table projecting forwardly from the lower part of the conduit, a broad horizontal steam-discharge slit located'sli ghtl y above the plane of the table, a similarly-shaped oil-discharge passage, said passage having its upper and lower edges curved downwardly to allow the oil in its flow to be impinged and atomized by the steam in its passage across the lip or table.

4. The combination in an oil-burner of a metal conduit having substantially parallel steam and oil passages with supply connections at the rear, horizontally-broad and vertically-narrow discharge-slits at the front, the oil-discharge slit being curved to cause the oil to impinge upon the horizontally-discharging steam from the slit below, a lip or table having transverse corrugations formed in its surface, said lip being located slightly below the plane of steam-discharge.

5. Anoil-burner comprising a metal conduit having wide rectangular substantially parallel oil and steam passages with supply connections at the rear, a substantially horizontal lip or table projecting from the lower part of the conduit, said lip having a transverse]y-corrugated surface, side retaining-walls and a segmentally-curved front edge, a horizontallywide steam-discharge slit slightly above the surface of said table, and a similarly-shaped- GEORGE E.
